IMPROVED MODE OF Rl-IGULATING MOTION OF RAILROAD-CAR TRUCKS.

Specification forming part of Letters Patent No. 46,316, dated February7, 1865.

To all whom it may concern:

Be it known that I, CHARLES SoHoUBERs- ZKY, of St. Petersburg, Russia,have invented a new and Improved Apparatus for Regulating the Velocityof Trains on Railroads, &c.; and I do hereby declare that the followingis a full, clear, and exact description thereof,

which will enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification, in whieh Figure 1 represents a longitudinal verticalsection of this invention, the plane of section The object of thisinvention is an apparatus which will regulate the velocity of trains onrailroads, to retard the velocity on declines, and to assist thelocomotive in drawing the trains up on grades.

The invention consists in the employment or use of two heavy fly-wheelssecured to the ends of an axle which rests either directly or indirectlyupon the driving-wheels of a truck in such a manner that by the actionof said fiy-wheels the velocity of the truck is rendered uniform, andthe momentum stored up in said fly-wheels when the truck is going downhill will assist the locomotive in drawing a train up on an incline.

A A represent the two fly-wheels, which are secured to the ends of anaxle, B. Said flywheels are made as solid and substantial as possible,their rims being by preference made ofstcel, so that they will becapable of running at the greatest possible velocity. The axle B ofthese fly-wheels is supported by four disks, a-two on each side of thetruck O-and said disks are mounted on the ends of axles b, which playfreely in guide-slots c in the longitudinal side timbers of the truck,as clearly shown in the drawings. The disks a are provided with hubs d,the inner ends of which form projecting flanges e, that rest upon theperipheries of the driving-wheels D. These wheels are constructed in themanner of ordinary car-wheels, and they are mounted on axles E, whichhave their bearings in oblique slots f in the side pieces of the truck,or in suitable boxes secured in said side pieces.

' The weight of the fly-wheels is thus equally divided upon thedriving-wheels and the tract ive power of said wheels is proportionatelyincreased. Furthermore, by the friction of the axle B on the disks asthe rotary motion of said axle is transmitted to the disks, and

through the disks to the driving-wheels, and if a rapid motion has beenimparted to the flywheels the truck moves along with considerable power.As the fly-wheels require a great mechanical force to change theirvelocity, the apparatus has such an effect on declines of the road thatit will absorb, or nearly so, the increase of velocity which otherwisewould be produced by the gravity, and in ascending grades the power thusstored up in the flywheels assists the locomotive in drawing tle train.

The operation of storing up power in this ap paratus while running onlevel portions of the road or on small grades can be effected by thelocomotive working with full power, and by its aid much larger trainscan be drawn upon the roads already existing than by the locomotives nowin use, or in constructing new roads the grades can be made much greaterwithout diminishing the weight of the trains. By admitting steepergrades the cost of earthworks, bridges, viaducts, and tunnels isconsiderably reduced, and the length of the road can be shortened, sothat the cost of construction would be materially diminished.Furthermore, since my apparatus will regulate the velocity of the trainin running down hill, there will be no necessity to use the brakes,which, when applied, cause great injury to the wheels and to the rails.In order to stop the train when the fly-wheels are in motion, the axlesof the disks to a are lifted up by wedges or other suitable means, so asto throw the flanges 0 out of contact with the peripheries of thedriving-wheels. On railroads with long and heavy grades, it would beadvantageous to apply a steam-cylinder to set the apparatus in motion,the steam being taken from the boiler of the locomotive.

it is obvious that instead of the frictiondisks between the axle of thefly-wheels and the peripheries of the driving-wheels other devices mightbe employed. The friction wheels might be dispensed with, or they mightbe a ranged in various different positions, and I do not wish torestrict myself in this respect to the particular arrangementrepresented in the drawings, but reserve the right to change those partsas convenience may dictate.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The fly-wheels A A, connected to an axle,

B, and supported by the peripheries of the driving-wheels of a truckwith or without intermediate friction'wheels, substantially as and forthe purpose set forth. CHARLES SOHOUBERSZKY. YVitnesses PETER Gon'rrn,NrooLAr ZIMINZ.
